That's my take. Atul Gawande (disclosure: I'm a big fan) takes his surgical mind to the problem and, as usual, illuminates the complexity of the issue. What if we had a system that allowed trash to back up into the streets if people didn't buy exorbitantly expensive "garbage insurance?" I suspect we'd move toward a system like what we have now: mostly affordable, in many cases government-subsidized trash collection. Healthcare could follow a similar model.

When I was a resident in the early oughts, vitamin D was the hottest thing going. We thought we were going to fix or prevent sooooo many problems by optimizing people's levels. Unfortunately, almost no intervention with vitamin D has proven successful. Vitamin D levels instead serve as kind of a generic marker of unwellness. Repleting those levels does not in and of itself fix the unwellness, though.
